Touch Products

Touchscreens are available in a wide variety of product families, sizes, shapes, and surface treatments to accommodate virtually any application and environment.
AccuTouch Five-Wire Resistive Touchscreens
AccuTouch technology with the harshest environments in mind, so it's no wonder that it excels in reliability, durability, and expected product life. Impervious to environmental conditions such as liquid spills and splashes, humidity, and washdown, these screens are the most contamination-resistant available. They deliver drift-free operation for a 35-million-touch lifetime.
IntelliTouch Surface Wave Touchscreens
IntelliTouch surface wave is the optical standard of touch. Its pure glass construction provides superior optical performance and makes it the most scratch-resistant technology available. It's nearly impossible to physically "wear out" this touchscreen. IntelliTouch is widely used in kiosk, gaming, and office automation applications and is available for both flat panel and CRT custom solutions.
SecureTouch Surface Wave Touchscreens
SecureTouch touchscreens use IntelliTouch surface wave technology and controllers in conjunction with extremely durable, tempered glass substrates. The result is an extremely tough, reliable interface for bank ATMs, ticketing machines, kiosks, gas pumps, and other demanding public access applications.
CarrollTouch Infrared Touchscreens
CarrollTouch infrared technology is the survivor of harsh applications. It's the only technology that does not rely on an overlay or substrate to register a touch, so it's impossible to physically "wear out" the touchscreen. CarrollTouch technology combines superior optical performance with excellent gasket-sealing capabilities, so it's an excellent choice for harsh industrial and outdoor kiosk applications. Touched with a finger, gloved hand, fingernail, or stylus, it delivers a fast, accurate response every time. CarrollTouch infrared technology is available for flat panel custom solutions.
Surface Capacitive Touchscreen Specifications
Capacitive technology consists of a uniform conductive coating on a glass panel. During operation, electrodes around the panel's edge distribute low voltage uniformly across the conductive layer creating a uniform electric field. A finger touch draws current from each corner of the electric field. The controller calculates touch location coordinates by measuring the current and transmits it to the computer for processing.
